When using the basic Twitch embed code in Firefox or Edge, autoplay works fine, but the stream always starts with the volume on, which is extremely annoying for our website visitors especially when a pre-roll ad starts.
Here is the current embed code that is not working (I had to remove the brackets to keep discourse from hiding the code):
iframe src=“https://player.twitch.tv/?channel=“channel name”” frameborder=“0” allowfullscreen=“true” scrolling=“no” width=“640” height=“480” autoplay=“true” muted=“true”></iframe
The stream DOES start muted in Chrome fine on all devices. Firefox and Edge, and possibly other browsers do not respect the muted=“true” option.
I already reached out to Twitch partner support, but they just told me to contact help here.
Am I missing something, here? Is this code out of date? Any help would be very much appreciated!
